Congratulations on your big decision!!! Good for you!!!!
Yes, it is common to have your legs feel like lead. Working out is one of the best things you can do for yourself...so good on ya for that, too!
Here's the Thomas Recipe:
At the bottom of the forum page, there is section that says "most viewed health pages"...and also a way to click on "see more health pages".
The Thomas Recipe (re-posted w/o a benzo) is found there. Two other health pages that may help you is the Amino Acid Protocol and Foods that increase Dopamine. I found a wealth of info reading many of those pages.
You're on your way......keep posting and keep on keepin on~
